The purpose of this test is to test whether lecturer notes are OIAable: was talking to it with a friend, and they said that they wouldn't be, because lecturer's regarded their notes as their own property, not the University's.

members of academic staff are explicitly covered in the definition of "Official Information". See also s2(4) OIA which calrifies that information held by employees in their official capacity (e.g. as a tutor) is held by the agency.
